无论是畅言还是多说,我都需要从远程抓取文章的评论数,然后存入本地数据库。对于多说,请求的格式如下:
代码如下// 获取评论次数,参数是文章ID
function getCommCount($postid)
{
$jsondata = file_get_contents("http://api.duoshuo.com/threads/counts.json?short_name=i94web&threads=$postid");
// 设置true返回数组,不设置或者是false则返回对象
$resjson= json_decode($jsondata,true);
return $resjson["response"][$postid]["comments"];
}
对于远程请求,有很多种方法。今天,LZ就搜罗了六种,供大家参考。
1、用file_get_contents 以get方式获取内容:
代码如下 $url="http://www.111cn.net/";$html = file_get_contents($url);
echo $html;
?>
2、用fopen打开url,用get方式获取
代码如下 $fp = fopen($url, "r");stream_get_meta_data($fp);
while(!feof($fp)) {
$result .= fgets($fp, 1024);
}
echo "url body: $result";
fclose($fp);
3、用file_get_contents 以post方式获取内容:
代码如下 $data = array ("foo" => "bar");$data = http_build_query($data);
$opts = array (
"http" => array (
"method" => "POST",
"header"=> "Content-type: application/x-www-form-urlencodedrn" .
"Content-Length: " . strlen($data) . "rn",
"content" => $data
)
);
$context = stream_context_create($opts);
$html = file_get_contents("http://localhost/e/admin/test.html", false, $context);
echo $html;
4、用fsockopen函数打开url,以get方式获取完整的数据,包括header和body,fsockopen需要 PHP.ini 中 allow_url_fopen 选项开启
代码如下function get_url ($url,$cookie=false)
{
$url = parse_url($url);
$query = $url[path]."?".$url[query];
echo "Query:".$query;
$fp = fsockopen( $url[host], $url[port]?$url[port]:80 , $errno, $errstr, 30);
if (!$fp) {
return false;
} else {
$request = "GET $query HTTP/1.1rn";
$request .= "Host: $url[host]rn";
$request .= "Connection: Closern";
if($cookie) $request.="Cookie: $cookien";
$request.="rn";
fwrite($fp,$request);
while(!@feof($fp)) {
$result .= @fgets($fp, 1024);
}
fclose($fp);
return $result;
}
}
//获取url的html部分,去掉header
function GetUrlHTML($url,$cookie=false)
{
$rowdata = get_url($url,$cookie);
if($rowdata)
{
$body= stristr($rowdata,"rnrn");
$body=substr($body,4,strlen($body));
return $body;
}
return false;
}
5、用fsockopen函数打开url,以POST方式获取完整的数据,包括header和body
代码如下 function HTTP_Post($URL,$data,$cookie, $referrer=""){
// parsing the given URL
$URL_Info=parse_url($URL);
// Building referrer
if($referrer=="") // if not given use this script as referrer
$referrer="111";
// making string from $data
foreach($data as $key=>$value)
$values[]="$key=".urlencode($value);
$data_string=implode("&",$values);
// Find out which port is needed – if not given use standard (=80)
if(!isset($URL_Info["port"]))
$URL_Info["port"]=80;
// building POST-request:
$request.="POST ".$URL_Info["path"]." HTTP/1.1n";
$request.="Host: ".$URL_Info["host"]."n";
$request.="Referer: $referern";
$request.="Content-type: application/x-www-form-urlencodedn";
$request.="Content-length: ".strlen($data_string)."n";
$request.="Connection: closen";
$request.="Cookie: $cookien";
$request.="n";
$request.=$data_string."n";
$fp = fsockopen($URL_Info["host"],$URL_Info["port"]);
fputs($fp, $request);
while(!feof($fp)) {
$result .= fgets($fp, 1024);
}
fclose($fp);
return $result;
}
6、使用curl库,使用curl库之前,可能需要查看一下php.ini是否已经打开了curl扩展
代码如下$ch = curl_init();
$timeout = 5;
curl_setopt ($ch, CURLOPT_URL, ‘http://www.111cn.net/");
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);
echo $file_contents;
